It's actually more the fact that players manage to bitch about the blight more than any in-game character does. And as Arrashi said already, the only one who was shown to passionately care about it was Garrosh and he did it for reasons that had shits to do with the weapon itself.
Honestly, I half-expected to see barrels of Blight flying around during the BFA trailer. I mean there were both Blight and catapults within the city. You can even see them in-game. One would think you would use everything at your disposal when your city is besieged.
It is cinematic and besides Sylvanas vs Anduin, Blizzard wants to recreate Orcs vs Human so blight could take too much spotlight.
I still hope we could see the use of blight in the opening scenarios, where Horde uses blight to destroy alliance catapults and alliance tries to disable the use of blight.
At least Sylvanas should blight the whole city when the battle is lost.
There should always be the line. If everyone just lets it loose then Jaina should have just destroyed Orgrimmar. It would be effective. It's not easy to not be hypocritical when trying uphold your ideals all the time but I don't think it's the reason to throw it all away either.
They'd lose the tauren instantly. They'd lose basically every single druid and shaman identifying themselves as a member of the Horde, since using the blight goes against everything they stand for. Let's be generous and assume every other member of the Horde has no issues with basically aligning themselves with Arthas 2.0. But they'd also have neutral factions, most notably the Argent Dawn, since they are in the neighbourhood, coming down on them. Even if the Horde wasn't weaker than the Alliance in the first place, which it definitely is, the scales would be tipped so much in Alliance's favor the Horde could pretty much start packing up for a journey off the face of Azeroth.
Of course, if it was a matter of life and death, if the Horde really had its back against the wall and it was a choice between using the blight and getting wiped out, I'm sure they'd get over it pretty easily. But using it on a large scale just because it's effective? Not going to go through.
And yet the last page was largely devoted to a Cenarion Circle Druid in Desolace using it against the Naga.
Because Arthas used Blight left and rights, apparently.
An idea totally supported by it not happening yet, despite Sylvanas using Blight and necromancy to fight the Alliance in the previous war.
The Horde is so much weaker that the Alliance had to cede Azshara to them in the last peace treaty even after the Horde imploded on itself, then lost less than Alliance since MoP ended. And in BfA they get stronger allied races.
Yes I hope they use it. Just to see it backfire on all the living allied with the Forsaken.
(note: this new plague =/= the old plague Arthas used)
I don't know, all you need to do is to aim it, just like any other weapon.
OT: The problem with blight is that its cruel and unethical. Other weapons are not like that. Take example at this ethical spell flamestrike icon:
Those dudes are having "blast". They are all like "Wow what a nice and humane way to die". With blight you can't have that.
Forsaken can clean the Blight after it's been used most of the times. And "hard to counter" covers pretty much all magic from lore perspective. Also, the Blight is an acid, it's a chemical weapon.
Turned into what? And why can't the Horde members not walk around the Blight puddles?
A chemical weapon that destroys surrounding life, it doesn't care if it's an ally. Why else do people in real life prohibit our governments from using biochemical weapons?
It's not something you could just clean and brush off. You had to kill bears and sailors due to its unexpected side effect.
Ignoring the quests I linked, and the fact that Horde and Alliance alike died in Wrathgate by the new plague.Turned into what? And why can't the Horde members not walk around the Blight puddles?
